Fan When you are cooking with the microwave the fan does not turn on. It also will not come on by manually turning it in. When you press the fan button it comes up "slices" on the display....any thoughts. Thanks

Only happens when cooking a big pot under the microwave? Hosing thermal fuse / thermostat kicks in to cool the microwave. Is the micro. Installed proper height above the range? Are you using the fan when cooking on the range?

"Boilovers cause smoking and greasy spillovers that may ignite and spread if the vent fan is operating.To minimize automatic fan operation, use adequate sized cookware and use high heat on surface units only when necessary."

And on page 20:

"If the temperature becomes too hot around the microwave oven, the fan in the vent hood will automatically turn on at the LEVEL 2 setting to cool the oven. The fan will automatically turn off when the oven has cooled down sufficiently. This is an automated process and cannot be turned off. The fan may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. The Vent Fan will only operate in 1~4 levels modes while the microwave is working."

The over the range microwave hood has a heat sensor in it. If it senses hot temperatures from cooking below it will turn the fan on. The fan will turn off once it cools down, this is to protect the microwave controls from damage.

This looks that the motor is not being functional, for that you have to look for the fuse if one. or else check the circuit if any wire is disconnected or burnt out accordingly you can decide what needs to be done.

"To prevent overheating from taking place, the exhaustfan is designed to automatically turn on at a low speed ifexcessive temperatures occur. Should this happen, thefan cannot be manually turned off, but it willautomatically turn off when the internal parts havecooled. The fan may stay on for up to an hour after therange and microwave oven controls have been turnedoff."

That;'s standard on microwaves.

But these models do have a separate internal cooling fan (which should run any time you microwave) plus the hood vent exhaust fan, which should only run when you select it, or if there is an excessive stovetop or under-hood temperature.

So if it comes on whenever you microwave, that is incorrect.

When that happens, it's usually a defective vent thermal switch (a.k.a. hood TCO).

But since it's brand new, I would certainly contact Magic Chef about this. If it's in need of repair, they will fix it free, assuming the oven wasn't physically damaged.

That's only covered in a very subtle note in the hood fan section of your owner's manual:

NOTE:If the temperature gets too hot around themicrowave oven, the fan in the vent hood willautomatically turn on at the HIGH setting to cool theoven. It may stay on up to an hour. When thisoccurs, the fan can not be turned off.

From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad.
Here are a couple of fan-related excerpts from the owner's manual, which can be found here:

Automatic Fan
An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat.
If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off.

Vent Fan
The vent fan removes steam and other vapors from surface cooking.
Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off.
Press the VENT FAN BOOST pad for extra fan speed.

Hope this helps.
